3D Models for 40140 Power Bank Cases and Holders

«3D Models for 40140 Power Bank Cases and Holders»

The reference shows holders and trays sized for 40140, 40135, 32140 and 32700 cells, alongside boxes for 18650 and 21700 packs. Some designs are simple cases that hold cells and wiring, while others include space for USB-C PD modules, BMS boards and switches. Multi-cell packs appear in series and parallel layouts, so the same power bank idea can be built as a compact unit or a larger block.

When choosing a file, check the cell format and count, the internal dimensions, and whether the model expects soldering, spring contacts or a battery holder. Look at the wall thickness, lid fit and screw bosses, because large cells add weight and can stress thin printed parts. On the author's page, review the material and settings they list, plus photos of real prints, to judge how the parts go together.

To refine the search, try terms such as 40140 holder, 40135 spacer, LiFePO4 power bank case, USB-C PD module box and 21700 pack enclosure. Related topics include battery trays, BMS mounts, panel-mount connectors and wiring channels. If a result is too specific, broaden to DIY power bank enclosure or cylindrical cell holder and then filter by the cell size you plan to use.
